SPECIFICATION forming part of Letters Patent No. 562,319, dated June 16,1896..

Application filed August 9, 1895. Serial No. 558,705. (No model.)Patented in England October 15, 1895, No. 19,300.

To aZZ whom it may concern.

Be it known that we, JAMES F. PLACE, a resident of Montclair New Jersey,and ER- NEST D. TERRY, a resident of Brooklyn,New York, citizens of theUnited States, have invented a new and useful Improvement in Vehicle orBicycle Lamps, (patented in Great Britain, October 15, 1895,No.19,300,)of which the following is a specification.

Figure 1 is a longitudinal sectional view of the lamp or lanterncomplete when fixed to a bicycle, showing our improvements. Fig.2 is alongitudinal sectional View of our im'- proved clamp attached to thehandle, showing its position when not fixed to a vehicle or bicycle.Fig. 3 is a top plan view, partly in section, of our improved air-supplyperforated annular disk below the burner, which also serves as thebottom to our new closed circular and imperforated burner galleryring.Fig. iis an elevation (outside view) of part of the lamp, showing wherethe wickshaft comes through the lamp-body and gallery-ring in theslip-joint where joined to the oil-fountg also one of the legs with ourimproved circular and imperforated wind-guard flange or skirt above thesame on lower part of our gallery-ring, which protectsthe horizontalair-inlet holes in the gallery bottom from wind-currents.

The object of our invention is to supply a steady volume of air to theburner without the flame being affected by outside wind-currents; tokeep the lamp c001, and to furnish a handy, yet positive, mechanism forfastening the lamp to the vehicle or bicycle; and to so connect thelamp-body and oil-fount together that they can be quickly put togetheror disconnected.

The following is a detailed description of our improved bicycle-lamp.

Referring to the reference-marks, 1 is the lamp-body.

2 is the oil reservoir or fount.

3 is the burner.

l is the canopy-top or Smokestack.

5 is the lens.

6 is the handle, (attached to which is the clamp 17,) which is connectedto the lamp body by the bracket 7.

All of the parts thus far designated may be made as shown, or of anyordinary design of lamp or lantern for outdoor use.

To the top of the oil-fount we fix a closed circular andimperforatedburner gallery-rim g 8, which incloses the burner around,the upper side ofwhich is arranged to form a closed slip-joint with thelamp-body at a point where the wick-shaft passes outside the ring, the

lower side of which ends in a flange windguard 14, and three legs 9, twoof which are shown in Fig. 1, and the third one in. Fig. 4. These legsare passed through the top of the oil-fount, and riveted or clenched at9. Within this gallery-ring 8, resting on the shoulder 10 above theimperforated flange wind-guard, we fix a perforated annular disk 11,which also forms the bottom of the gallery-ring, below the burner. Thisdisk has a raised annular portion 12, and in and around the sides ofthis annular raised part are one or more circles of horizontal inletair-holes 13 and 13', which pass in through the disk horizontally to theinside of the lamp-body, below the burner.

It will be noticed that the ring 8 has around it a circular imperforatedflange skirt or wind-guard at 14: above the top of the legs 9 and belowthe said gallery bottom and its raised annular part. This is for thepurpose of breaking any wind'currents and protecting the holes 13 and 13from such currents.

The air passing in under the wind-guard 14 circulates around the legs 9and over the top of the oil-reservoir 2, thus absorbing the heat of thesame, and keeping the oil in the fount 2 cool. The air to supply theburner passes up into the annular raised part 12, and is drawn throughthe series of horizontal holes 13 and 13, and strikes the inside of thering 8 and the outside of the burner 3 in a large number of horizontaljets, thus taking up the heat of those parts. The force of theair-currents is also much broken as there is an outward current of airagainst the inside of the ring 8, and an inward current of air againstthe burner 3 at its base, so that the air, as it takes an upwarddirection and rises to the burner, is delivered evenly and withoutsufficient force to affect the flame. It will be noticed that all airadmitted below the burner is forced in between said circular flangewindguard and the top of the oil-fount, as the circular gallery-ring 8as well as said flange skirt or wind-guard is closed to the admission ofair, beingboth imperforate. This is an important feature of ourimprovement.

To the handle 6 is attached the clamp 17. Within this clamp is a movablesteel plate 21, which is held in place, and against the short end of thecam-lever 18, by the rubber cushion 20, which incloses the ordinarylampbracket 19 belonging usually to all bicycles. This cam-lever 18 hasa short end 23, which is within the clamp 17, and rests against thesteel plate 21. It also has a long end outside of said clamp, which isbent downwardly nearly at right angles to said short end 23. Between theshort and long ends of this camlever is a horizontal fulcrum-pin 22,which is fixed to the clamp, as shown. This fulcrumpin passes throughthe cam-lever at a point between the short and long end, or where itpasses in through the wall of the clamp, and said cam-lever turns onsaid fulcrum-pin as on an axis.

In Fig. 2 the cam-lever is shown in its normal position when the lamp isnot fixed to the bicycle. In that position the rubber cushion pressesthe steel plate 21 back against the wall of the clamp and allows thebracket 19 to be easily inserted between the two folds of the rubbercushion. By pressing down the long end of the cam-lever 18, the short orcam end at 23 is raised upwardly and forces the steel plate 21 forwardinwardly against the rubber cushion, and the bracket 19 is firmlygripped between the folds of the rubber cushion, as shown in Fig. 1, sothat the lamp or lantern cannot be removed from the bracket until thelong end of the cam-lever 18 is raised, as shown in Fig. 2.

The oil-fount, with gallery-rin g fixed thereto, as described, is madedetachable from the lamp-body at a point where the wick-shaft passesoutside the ring, as shown in Fig. 4. The upper side of the gallery-ringis made slightly larger in diameter than the lampbody, and in connectingto the lamp-body it slips over the lower edge and thus forms a closedslip-joint.

Having thus described our invention, what we claim as original, anddesire to secure by Letters Patent, is-

1. In a bicycle-lamp, the combination of a lamp-body and a detachable.oil-fount, with an imperforated burner galleryring surrounding theburner, its upper side arranged to form a closed slip-joint with thelamp-body at a point where the wick-shaft passes outside the ring, andits lower side having a flange wind-guard, with legs connecting same tothe oil-fount; a disk forming the bottom to said imperforatedgallery-ring; a raised annular part in said bottom having circles ofhorizontal air-inlet holes, whereby the said horizontal air-inlet holesare protected from air-currents, and all air admitted below the burneris forced in between the said circular flange wind-guard and the top ofthe oil-fount, substantially as shown and described.

2. In a bicycle-lamp, the combination of the lamp-body, with handleattached to the same, of a clamp attached to said handle and a movablesteel plate within said clamp, held in place by a rubber cushion; acam-lever having a short end inside the clamp, and resting against saidsteel plate, and a long end outside said clamp bent downwardly at nearlyright angles to the short end; a horizontal fulcrum-pin fixed to saidclamp and passing through said cam-lever and between the ends thereof,whereby pressure exerted downwardly on the long end of said cam-leverforces the short end upwardly against said steel plate and causes saidplate to move forward inwardly and grip the lamp-bracket within therubber cushion, substantially as shown and described.

In testimony that we claim the foregoing as our invention we have signedour names, in presence of two witnesses, this 7th day of August, 1895.
